Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15175 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 7, Soil and site

NOTE 1 The sources can be for example cars, application of substances through agricultural practices, emissions from
town or region, deposition through flooding of a river.

3.7
point-source input
input of a substance from a stationary discrete source of defined size
NOTE 1 The sources can be stack emissions, accidental spills, waste dumps, spills on industrial sites, major leaks
from sewers and other pipelines.
NOTE 2 Point-source input can cause both locally contaminated sites and relatively uniformly contaminated sites.

pollutant
substance or agent present in the soil (or groundwater) which due to its properties, amount or concentration
causes adverse impacts on soil functions or soil use

4 General
Soils are of central importance within the water cycle because their storage and filter functions have a lasting
influence on the water balance and groundwater quality. In this context, particular attention shall be paid to the
following functions:
 mechanical filter functions (retention of suspended sludge and pollutant particles);
 chemical filter functions (sorption and mobilization of substances);
 transformation functions (degradation or transformation of substances).
Soil is understood as a porous medium consisting of three phases: the solid phase, the liquid phase and the
gaseous phase. The ratio of these phases and their respective compositions vary widely in time and space.
The assessment of contamination affecting groundwater quality requires a profound understanding of the
governing processes and reactions of potentially toxic compounds in soils. Contaminants are translocated in
all three phases of soils as a function of the properties of the chemicals and the soil. Hence strategies for
assessing risks to groundwater due to soil contamination should vary with the contaminants considered, and
should take into account those soil properties which mainly govern the soil's filter, retention, release and
transformation functions.
In addition to considering the properties of the chemicals and the soil governing the behaviour of contaminants
in soils, different ways for contaminants to enter soils shall also be evaluated when designing suitable risk
assessment strategies, with respect to contamination of groundwater. Soil and groundwater contamination
can be caused by different sources on different spatial scales, as indicated in Figure 1. On regional and larger
scales, soil contamination is caused, for example, by wet and dry atmospheric deposition and has
predominantly diffuse character on a moderate level of contamination. On a local scale, a variety of point
sources can cause all kinds and magnitudes of soil and groundwater contamination. Most point sources of
contamination may also be regarded as off-site diffuse sources of groundwater contamination. It is evident
that different contamination scenarios as a function of contamination sources and scale demand different
investigation strategies with respect to groundwater impact. At present there are no uniform principles for the
investigation and evaluation of contaminated soils and contaminated sites in relation to the protection of water
resources.

Investigation strategies may be qualitative or quantitative. Qualitative approaches mostly refer to assessment
of, for example, the potential leaching risk of chemicals through the soil towards groundwater. In contrast to
quantitative approaches, the level of actual soil contamination is not taken into account. Approaches of this
type can also be utilized, e.g. to classify larger areas with respect to their capability of protecting groundwater
resources against contamination, or as an introductory step in an assessment of an actual contaminated site.
